While working on a separate problem, Hippasus is said to have stumbled on the fact that an isosceles right triangle whose two base sides are 1 unit in length will have a hypotenuse that is √2, which is an irrational number. (This can be shown using the famous Pythagorean theorem of a...
What's in pi?If you've ever used n in math class, you probably used the number3.14. In fact, the number for pi is much longer. n is called an irrational number (无理数) because the digits (数位) after the decimal point (小数元点)never end or repeat.In 2015, a young man from...
Pi is a number that relates a circle's circumference to its diameter. Pi is anirrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits...

Hence between any two numbers a and b there are two rational numbers, and between those two rational numbers there is an irrational number. This proves that the irrationals are dense in the reals. What are dense real numbers? Let X ⊂ R X \subset \mathbb{R} X⊂R. A subset S ...
